Specification of Letters Patent.

Patented Apr. 15, 1919.

Application filed May 23, 1918, Serial No. 236,197. Renewed March 6, 1919. Serial No. 281,061.

To all whom it may concern:

Be it known that I, O'r'ro E. KOPPLIN,

born in Germany, but since four years old and for over thirty-four years a resident of Marion, in the county of Guadalupe and State of Texas, have invented certain new and useful Improvements in Plows, of which the following is a specification, reference being had therein to the accompanying drawings. I

This invention relates to improvements in plows, and has for its object the construction of a simple, durable, and efficient'plow that embodies a number of adjusting devices for adapting the plow to a nicety to perform its functions to accomplish the best results.

With this and other objects and advantages in view, my invention consists of certain novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed. 7

' In the drawings:

Figure 1 is a perspective view of aplow constructed in accordance with the present invention.

Fig. 2 is a perspective view of the plow looking at therear thereof.

Fig. 3 is a view, in side elevation, of my plow.

Fig. 4 is a top plan view of my plow.

Fig. 5 is a sectional viewtaken on line 5 5, Fig. 4 and'looking in the direction of the arrows.

- Fig. 6 is a sectional view taken on line 6-6,Fig. 4, and looking in the direction of the arrows.

Fig.7 is a fragmentary view, in side elevation, showing particularly the tongue vertically adjusting device.

Fig. 8 is a sectional view taken on line 88, Fig. 7, and lOOklIfg' in the direction of the arrows.

Fig. 9 is a fragmentary perspective view of the adjusting device for one of the wheels. Referring to the drawings by'numerals, 1 designates the frame of my plow that is provided, at the right-hand end, with a pair of horizontal, parallel, elongated slots 2, 2.

In these slots 2,2 are bolts 3 and 4, which bolts 3 and 4 are provided with the usual head and washers and nuts, as shown, for holding the inner ratchet plate 5' and the outer ratchet plate 6 secured to the frame '1. The outer ratchet plate 6 is provided with a stub-shaft 7 upon which is journaled the wheel 8. By reason of the slot .9, bolt 3 or inclination of the right-hand wheel 8. It

is to be understood that the bolts 3 and 4 may be adjusted longitudinally in the parallel slots 2, 2, whereby the wheeli8 may be positioned transversely of the frame 1 for placing the wheel near to or farther from the frame, as desired. V

The left-hand wheel 10 is journaled upon a crank shaft 11, which crankshaft 11 is square, at its inner portion 12, and the square inner portion is retained in a sleeve 13, and sleeve 13 is journaled in the casing 14, which casing is fixedly secured to the frame 1. A suitable collar 15 is detachably secured upon the squared portion 12 of the crank axle 11, and the crank .axle 11' can be rotated, through the medium of 'frame 16 and lever 17; the frame 16 is fixedly secured to the squared portion 12 of the crank axle 11, so that upon gripping the lever 17 and raising its ratchet from engagement with ratchet plate20, the frame 1 can be.

lowered or raised with-respect to the ground by causing the crank shaft ,11 to be rotated upon the frame 1. The ratchet plate 20 of the left-hand adjusting-device is bolted, at 21, to. the frame structure, and this bolt 21 also secures the inner 'end of the angular bracket 22, fixedly secured upon the frame.

The bracket 22 has its upper end 23 overhanging the central part of the frame (Fig. 5) and this upper end 23 of the primary bracket fits over the upper threaded end 24 of the central, vertical post 25, which post 25 has its lower end extending through the body of the framel, as shown. Slidably mounted upon the post 25 is a sleeve 26, that is integral with a plate 27 which plate 27 is bolted, at 28, to the plow beam'29. The lower end of the plow beam .29 carries a mold-board 30.

shaft 31, upon which shaft 31 is mounted the roller 32. The roller 32 is retained upon' through the medium of a cotter The roller 32 works inthe slot of 34, which camarm 34 1s fixedly shaft 31, pin 33. cam arm' secured to the lever 35, and the lever 35 is e provided with the usual spring pressed catch device 36 that engages the ratchet plate 37. Theplate 37 is-fixedlly secured to the up-standing extension 38 of the frame By l ng the lever 35 upon the ratchet plate 37, the'cam arm 34 will be swung in a vertical plane causing the roller 32 to travel in said cam arm, thereby raising and lowering plate 27 and sleeve 26, which, in turn, will raise or lower the plowbeam 29 with respect to the frame 1, so that agreater or less depth for the mold-board 30' will be obtained. By reason of the :pe-*

cu-lia-rstructnre of the plow beam adjusting device, I found from actual experience that a very durable structureis obtained, since a minimum number of parts are involved, and

which parts are strong, and efficient.

The. tongue- 39 '(Fig. 7) is pivotally connected by bolt 40 to the, plate 27 and the tongue is positioned in a primary bracket 41 .thatis secured, at 42, :tothe front end of the plow beam '29. Also secured to the front end of the plow beam '29 is a .clevis device 43. An auxiliary bracket 44 is positioned around the tongue 39 (Fig. 8) and the upper end of the bracket 44 is provided with. an integral, horizontal extension 45,-,

which extension 45 has a-pair of inwardlyextending. lips '46-, which lips 46-fit over the flanged edges '47 offithecurved lower end 48 of the tongue vertically-adjusting lever 1 49 (Fig; 7). The inner end of. the lever. 49'

is pivotal'ly connected to the bracket '44,: by. means of bolt structure '50, so that when lever '49 is shifted along the ratchet bracket 51, attached, at 52-, to tongue 39" (Fig.17) the ztlanged'edges 47 will ride under lips- 46 of theeXtension 50 whereby the tongue 39 may he vertically adjusted with respect to the plow beam 29; Itwil'l' be understood that-through 'themedium of the tongue ad justing lever 49 and its cooperating parts, an

independent vertical adjustment of. the tongue 39 is obtained, other than the bodily adjustment of the -tongue with the'bodilyadjustment of the plow beam '29, when the lever 35 is operated, for lifting the entire plow lbeam 29,.mol'd-board 30, and tongue 39, as previously described.

A n auxiliary adjusting device for the tongueis provided in-my plow, which'in' volve's a ratchet plate '53 (Fig. 5) that is secured, through the medium of bracket r54,

tothe primary bracket 22; (Fig. The

usual shifting lever '55 is pivotally mounted,

at 56,-upon the ratchet plate 53, and to'the lower end of lever 55, at 57, isattachrid the hooked end 58 Fig.- 4) of link 59, the outer end ofj'link 59' being also-provided with :a'

' hook'th'at is positioned in'the eye plate 60,

which plate 60 is attached to "the plow be'a-m" 2'9, near its forward end, consequently". by

shifting the lever 55 upon the ratchet "plate 53, the lower end 'wil lcanse the link te swing the tongue 39 transversely of the plow, as clearly shown by dotted lines 61 (\Fig. 4 i

The primary bracket 22 is braced, near its middle, by a vertical bolt 62, which bolt 62 not only extends through bracket 22 (Fig.- 5) but through frame 1, the lower end of bolt 62-extendin-g through a transverseplate 63, thereby materially strengthening the entire bracket 22 by reasonof making the structure rigid'and thereby eliminatingany play or unnecessary swinging of the bracket near its middle, as might be likely when, plowing heavy or rocky ground.

- A seat -64'is carried upon the upper end of seat-standard 65, which seatstandard is 43 Fig. 7) "is positioned a bolt '71, and attached to bolt '71,. isan eye bolt 172,. and. :in

this eye-bolt 72 is lffijStGIlGdzOIIQ-G'Hd of coil spring 73, the other end ofwcoil spring "73 being attached toahook- 174, which hook is suitably attached to frame 1.- 7 The spring 73 exerts normally a downward pull upon the forward end of "the: plow beam 29, through the medinmcof thereleveis device 43,

From the. foregoing description, it is tobe understood that I have provided a plow with independent devicesfor adjusting the wheels supporting the frame, and that" I have also provided, onithe frame 1, a bodily vertically adjustable device for the entire plow beam, mold-board and point, as well as the tongue 'Fiurtherfit will ibe -understood from the foregoing description, that I have provided an independent vertically adjustable device for swinging the tongue and also another device for swinging the tongue in a horizontal plane or transversely to the frame,
